Trying to write it all day long with Revelprog but always at the end verification failure.
I can read the backup of my laptop and rite as many times as I want but this one not.
And is this clean BIOS without enrollment ?

Attached is the read backup from my laptop which is enrolled to a school

thanks

You need to select 1.8v chip in programmer

Thanks for good advice which I never tried, but with 1.8 volt chip is not detected at all, by default this chip is selected as 3v in revelprog, but I tried lowering manually the voltage until 2.2 volt, but again the same , unable to write the chip.

Also what is most interesting is that the backup I have made from the chip is written as many times as I want, only other backups no

I attached the read backup from my laptop. If you can find just the serial number or what is needed to be changed so that it doesn't ask anymore for enrollment, I would appreciate it very much, cause the file above that you have given no chance to write. But this backup that I made can write as many times as I want

Flashchip is:Winbond 25Q128JVPQ

thanks
